IMPROVEMENT IN LAMP-SHADES.

The schedule referred to in these Letters Patent and making part of them To all may concern:

. Be itknown that I, 'FREDEBICK E. FOSTER, of Oressona, Schuylkill county, Pennsylvania, have invented an Improved Lamp-Shade; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention consists of a light metal frame, on which is stretched oiled paper, or its equivalent, and

which is adapted for attachment to and adjustment specification, and. in whichgigure l is a sideview of my improved lamp-shade, an

Figure-2, a front view of the same.

A is the burner, and

B, the chimney of an ordinary coal-oil lamp.

A rod, 0, the inner end of which is forked, and clasps a burnerfA, projects outwardly from the latter, and 'a metal ring, D, from which projects a similj 5:1 rod, E, is

slipped over the top, and rests against the swelled portion of the chimney, clamps c projecting'from the side of the ring, and assisting to maintain the same in its proper position.

To the outer end of the rod E is hinged alight metal frame, F, and within the latter is secured, by clips x, a frame, F, of bent wire,'0ver which is stretched a sheet of oiled paper, or other translucent materialor membrane.

At the under side of this frame is an eye, e, through which passes the lower rod, 0, a knob, f, at the end of the latter, serving to prevent the eye from slipping The frame F may be adjusted to any'desired angle the lower rod, 0, to the required distance, the rod E, to which the upper portion of the frame is hinged, readily accommodating itself to any change in the position of the frame.

While the frame F can'be adjusted so as to throw a shade at any desired point, it will be retained firmly in its positionafter adjustment, while, owing to the manner in which the frame is-secured, the use of the are liable to get out of order, is avoided.

Should the paper, or other membrane covering the frame F,- be injured, the frame F may be readily detached, recovered, and replaced, or another frame, having a difierent-colored membrane, may be substituted for the one first used, when desired.

instead of being hinged to the upper, it may be jointed to the lower rod.

I do not claim, broadly, a shade in combination with devices whereby it maybe adjusted at different angles in respect to a burner; but

; I claim as my invention, and desireto secure by Letters Patent- 1. The frame F, hinged at one side to the bar E, and having at the other side an eye, 0, through which passes a forked bar, 0, all as and for the purpose described.

2. The frame lents, and adapte for the reception of a-detachable frame, F, covered with translucent membrane, sub stantially as and for the purpose set forth.

.In testimony whereof, I have signed my name to this nesses.
